⚡ Reliability
Best When
You're a B2B SaaS company that wants to leverage your G2 presence programmatically — embedding reviews, tracking buyer intent, or monitoring competitive positioning.
Avoid When
You sell physical goods, services, or anything non-software — G2's platform and trust signals don't apply outside B2B software.
Use Cases
- • Embedding verified G2 review widgets and star ratings on SaaS product pages to increase conversion
- • Pulling buyer intent data to identify accounts actively researching your product or competitors
- • Monitoring new reviews in real-time and routing to CS or product teams for response or feedback loops
- • Competitive analysis — pulling review sentiment and feature scores for competing products
- • Feeding G2 review content into sales enablement tools or AI agents for objection handling
Not For
- • Consumer product reviews — G2 is strictly B2B software; use Yotpo or Bazaarvoice for physical products
- • Local business reputation management — Google Business Profile or Yelp are correct for local
- • High-volume programmatic review collection at scale — G2 reviews are user-submitted, not API-collected
Interface
Authentication
API key authentication via Bearer token header. Keys are provisioned through the G2 My Products dashboard. Access to intent data and advanced endpoints requires G2 Buyer Intent subscription on top of base API access.
Pricing
API access is bundled with G2 paid listing tiers. Buyer intent signals are a premium add-on with significant additional cost. Review and rating data on free listings is very limited via API.
Agent Metadata
Known Gotchas
- ⚠ API access level is tied to your G2 listing tier — check what endpoints are available on your plan
- ⚠ Buyer intent data requires a separate expensive subscription — confirm before building agents that rely on it
- ⚠ Review data for competitor products is limited — you primarily get rich data for your own products
- ⚠ Annual contract required for most useful features — no month-to-month for intent data
- ⚠ Webhook events are limited to new reviews on your product — no cross-product event streaming
